Calling the Lock Functional Module 

Use

You have to call the functional module RSCAF_TABLE_LOCK before running the extraction process for DataSources created for entity service queries. There are no locking mechanisms in place for queries from application services.

You run the functional module table lock with the LOCK_FLAG=0 and I_BEI_LIST variables with values that define entity services or several services. After the extraction process is completed, you can execute the functional module with the values that define the entity service.

Procedure

 

       1.      Launch the Function Builder from the SAP GUI.

       2.      In the Function Module field, enter RSCAF_TABLE_LOCK and choose Display.

■       1 = unlocking

○       Click  next to 0 Entries(I_BEI_LIST) and enter the following values:

■       E_VENDOR – sap.com

■       E_APPLICATION – caf.tests

■       E_NAME – StudentService

○       Choose  with the quick info Back to return to the initial screen.

○       Choose   with the quick info Execute to test the function module.

       5.      To verify that the entity service was either locked or unlocked (as per your definition), use the CAF test servlet.

       6.      Use the functional module test directory to store test data for use at a later time.
