Error while creating APD
I have problems creating the APD, am getting the error message mentioned below while activating the APD.
The APD uses a query output as a data source and application server as the data target.
Error message is as follows:
"The technical field name KYF_0001 for field 4GIEM34ATXX4FN5L9UK4LZ797 may only appear once per input or output structure
Message no. RSAN_WB010
Technical key for message: CX_RSAN_SVC_CHECK_ANALYSIS_N=>NODE_FIELDNAME_NOT_U
If you require further assistance, look for a SAP Note containing the key words CX_RSAN_SVC_CHECK_ANALYSIS_N=>NODE_FIELDNAME_NOT_U or RSAN_WB010.".
Searched the relevant sap notes..but still couldn't find anything relevant. All the relevant sap notes are about the query output being large.
I am aware of the restrictions while we use Query as data source...that is 2 structures..made modifications still didn't work.
