Introduction Process chains are a robust graphical scheduling & monitoring tool to maintain automation, visualization & monitoring of tasks/processes.

3 Introduction Process chains are a robust graphical scheduling & monitoring tool to maintain automation, visualization & monitoring of tasks/processes. These chained processes are designed to carry specific tasks. Process chains are integrated into CCMS, which is in turn integrated into portal based BI administration cockpit. What Process Chains does is simply automate complex tasks/process scheduling, visualization of these processes plus central controlling of these tasks (either in same or linked process chains). If a process chain isn t available for a specific task, SAP provides customers with an easy way to create custom process types, wherein one can still run customer programs using Business Content ABAP process types. A process chain consists of a start process, individual application processes and the so-called collection processes. The application processes are the actual processes. SAP BI supports process types like load process and post processing processes, Data target administration processes and other processes Fig. A. An Example of a Sample Process Chain Version M of process chain IC3_PC Usage of Process Chains Process Chains are similar to flowcharts which are scheduled to be waited in background & triggered for a event (or for starting further other processes) by a process. Here we need to list all Info packages, DTPs that's necessary to load the data, which can be either a full load or delta load, following which these chains are scheduled (Viz. hourly, daily, monthly, etc, depending on business requirement). So, before creating process chains, we need to keep the process flow perfect (i.e. the links between BI objects like Info package, DSO, Cubes etc) in the BID system. This process chains can be used to automatically load attribute/hierarchy etc, wherein in procedure these are listed as application process SAP AG 3

Process chains in SAP Business Intelligence Previously in 3.x, we had used Event chains, automatisms and process chains for automating processes, which had a lesser flexibility. In SAP BI 7.

Processes chains are necessary to support those processes which are sometimes complex & parallelization plus where branching for status-dependency is necessary.

4 Process chains in SAP Business Intelligence Previously in 3.x, we had used Event chains, automatisms and process chains for automating processes, which had a lesser flexibility. In SAP BI 7.0, the existing automation functionalities are backward compatible, but now automations are not longer used for transformations & data transfer processes in SAP BI 7. Processes chains are necessary to support those processes which are sometimes complex & parallelization plus where branching for status-dependency is necessary. We can divide a process chain into several sub processes which enable us to administrate it better for sake of clarity & effective management. Process Chain Views In a processes chain, within a particular time slot all the respective time dependencies are bundled together, and they offer central controlling & monitoring of all processes steps defined in them. Process chain maintenance can be reached via Data Warehousing Workbench or via the transaction code: RSPC, which offers different views on process chains. Planning View: Using click, drag and drop, the process chain is designed at this stage. All the existing process chains and definition of process chains can be overviewed here and here in the planning view all the process chains are created & maintained. Checking View: The process chain is checked for errors. We can view this using the control Ctrl+F2 in RSPC, where the results from the testing (both syntactical and semantic) are defined in the plan view, so as and when some changes are made respective process chains are executed. Log View: The results of each run are monitored. In this log view, we have the details of the process chain selected on the plan view. Step-by-Step Guide Step 1: Creating a Data Model Create a process flow model for data to be loaded into some provider (say Info Cube/DSO). In the following diagrams we will see how to create one. Fig Initially we first create an Info area (as in above example) in RSA1 (Data warehousing workbench), following which we create an Info cube SAP AG 4

Fig.1.2 It s to be noted that Info cube we have considered for demo has a template as SAP Demo cube. (SAP Purchase Cube: 0D_PU_C01). This cube we created abstracts only skeleton of original cube.

Before that care must be taken to change the Source system type (say, BI, File and Web Service etc) Fig.1.4 Further to it we create a Data source.

5 Fig.1.2 It s to be noted that Info cube we have considered for demo has a template as SAP Demo cube. (SAP Purchase Cube: 0D_PU_C01). This cube we created abstracts only skeleton of original cube. Choose Create Application Component Fig.1.3 Now, we go to Data sources, wherein here we create an application component. Before that care must be taken to change the Source system type (say, BI, File and Web Service etc) Fig.1.4 Further to it we create a Data source. Right click the application component area & create a Transaction Data type data source, which is from a source system called FLAT_FILE. Fig.1.5 The data source (As in example: ds_gods) has the above settings as extraction parameters. Here, we are loading the file from Application Server (Viz. AL11), so we have chosen the adapter as Load Text- Type File from Application Server. Following this here this being a fixed length format & usage of delta process we choose the respective options as stated in above figure. Step 2: Accessing Data from AL11 Fig.2.1 After choosing to load data from Application Server folder, we ll be prompted to choose data from 2 options as in above figure. We now choose AL11 files & proceed to choose DIR_HOME 0D_PU_C01_TD_2003_2004.csv, which is a test data in the AL SAP AG 5

03_2004.csv) Fig.2.3 Click on Load Example Data in the Proposal tab of data source (as in example: ds_gods) & start we can

6 Fig.2.2 The AL11 Application server files would look something as this. Herein we need to proceed to Copy name option to choose particular test data file (0D_PU_C01_TD_2003_2004.csv) Fig.2.3 Click on Load Example Data in the Proposal tab of data source (as in example: ds_gods) & start we can see as in right side list of all fields, its description, data type & length. Trouble Shooting: It s to be noted that here not all fields are copied. If you scroll down, you d know why SAP AG 6

Following this we see a preview as below.

7 Fig.2.4 Here we need to fill up these values in the template as in the field names in the particular data source. We need to update the information here & activate. Following this we see a preview as below. Fig.2.5 Read preview data option is clicked & data is viewed as below in Preview tab of the data source. Fig.2.6 Create an Info package followed by writing its description 2010 SAP AG 7

8 Fig.2.7 We must not start this now, that s what we intend to do using process chains. Step 3: Creation of Transformation Fig.3.1 Create a transformation with the target info providers (Cube: TEST_B2) & data source names. Fig.3.2 Once done, the next step is to create a Data Transfer process, by right clicking the cube & creating a DTP as shown in above figure. As above i.e. for transformation, we have the source as Data source (DS_GODS) & target DTP as Info Cube (TEST_B2) (Pl. refer figure 3.1 reg. transformation) SAP AG 8

Step 4 - Process Chain Planning Fig.4.1 Start Transaction code RSPC.

Click on Create & enter the name of the process variant & long description for the same. Now once done, click on command button Change Selections 2010 SAP AG 9

Fig.4.2 in start time panel there are a list of options like Immediate / Date-Time / after Job / after Event etc. We need to choose the appropriate scheduling the process chain requires.

Direct Scheduling: The job will be scheduled when the process chain is activated 2. Start using Meta Chain or API: No triggers are scheduled.

In our example, we are processing single process chain, so we ve chosen Direct Scheduling Fig.4.4 Enter name of start process for the particular trigger; each process type is very generic.

10 Fig.4.2 in start time panel there are a list of options like Immediate / Date-Time / after Job / after Event etc. We need to choose the appropriate scheduling the process chain requires. For demo purpose, we ve chosen Immediate as the option & click on Save Fig.4.3 The top row displays the name of variant, details like last changed by etc. There are 2 options like 1. Direct Scheduling: The job will be scheduled when the process chain is activated 2. Start using Meta Chain or API: No triggers are scheduled. The start of the process chain will be done via FM, RSPC_API_CHAIN_START or with another process chains. In our example, we are processing single process chain, so we ve chosen Direct Scheduling Fig.4.4 Enter name of start process for the particular trigger; each process type is very generic. Example: Load data into an Info cube. Here, each process needs a variant, which tells us the process exactly which objects to work on. Fig.4.5 A special type of process is the Start process. Every chain must have one. Again, a Start process without a variant is worthless. The variant provides information about when to start SAP AG 10
