Hi
Have you transfered the SPL index to TREX? The error could be due to no SPL Indexes in TREX Server, if you didn't transfer complete SPL indexes to TREX server.
Ensure that you have regenerated the index and that it has been transfered fully to TREX:
1. Reset Buffers - /SAPSLL/SPL_CUS_APP_BUFF_RESET
2. Generate Comparison Terms for SPL - /SAPSLL/SPL_CREATE_SEARCHTERMS
3. Aggregate Comparison Terms - /SAPSLL/SPL_INDEX_CREATE
4. Generate Comparison Terms for Bus. Partners -
/SAPSLL/SPL_CREATE_SEARCHTADRC
5. /SAPSLL/SPL_STTREX (Upload Comparison Index to TREX)
Please execute T-Code '/SAPSLL/SPL_STTREX' to transfer SPL indexes without p_delta selection
option.
I hope this helps.
Kind Regards
Ann Marie
