Error 9 in Update when loading data in RSA1

Dear Experts,

We have a strange issue here. We refreshed our BW box with production and performed all the steps correctly without any issues.

After that when we are trying to do a data load test from RSA1 for certain infocubes, we see this error:

We faced this error previously also by applying these fixes:

1. As our production had TREX and this box doesn't have that, so with RSCUSTA we deleted the TREX RFC which was there.

2. As our production had TREX and this box doesn't have that, so with RSDDBIAMON2 we Switched-off Index Searching.

3. We applied the note 1662548, which exactly deals with this problem.

But this time, even after applying the above fixes as well, we are not able to solve it. We checked SM58 and WE02 in both BW and Source System but found no anomalies. Everything is "joyfully green" .

Kindly advise.

Thanks,

Avishek
