Question

Hi All
Iam triyng to do, LO Extraction on SD Sales Document Header Line ( 2LIS_11_VAH ) and customizing the Extract Structure  by adding more fields like MCVBAK AEDAT,NETWR and KOSTLC.I get erorr when I transfer the  above fields to Extract Structure as
"Struct App 11cannot be changed duetosetuptable--> Long Text" which means that extract structure is not getting updated .
Please advice in order to reflect the change ini extract structure under Maintenance.

Hi
Another way to enhence data source by appending the required fields directly to the communication structure(i.e. MCVABK, MCVBUK etc...) and then write user exits to populate these fields, then go to the LO cockpit and move appended fields from communication structure to extract structure.
This is the standard procedure to enhence the data source which is recommended by SAP.
Previous one which you have used is mainly used when we need not to catch the deltas for the enhanced field but if there is requirement to catch the deltas for appended fields the only way to append the fields in communication structure.
