Cacher is the code snippet organizer for pro developers

Integration into ABAP Programs.

 The 5 basic steps involved are -

 1.Data retrieval in the report programme.
 2.Call Function 'FP_FUNCTION _MODULE_NAME( to get the  generated
    function module name).
 3.Call Function 'FP_JOB_OPEN '.
 4.Call Function <generated function module name>.
 5.Call Function 'FP_JOB_CLOSE'.

 If you need to have copies of the same form to be generated, you may call
 the function module by using (do ('n' times) - enddo) loops.

 There are standard test forms for training provided by SAP. Search "FP*"
 in the SFP transaction.

Troubleshooting 
 Features
  You are provided with various function modules for troubleshooting purposes.
  You can use these function modules to extract the following information:
  Texts about the cause of the error (with the FP_GET_LAST_ADS_ERRSTR FM)
  A trace of the Adobe document services (with the FP_GET_LAST_ADS_TRACE FM)
