EHP6 to EHP7 Upgrade Issue: Junk Values are showing for BW data source

Hi,

We are upgrading ECC from EHP6 to EHP7. We have custom data source which is build on custom Info set and Info set is built on Pooled table ZXXX. Datasource is showing the junk values in RSA3 after upgrade. I have re-generated the Info set and tested but no use. Below is the RSA3 data screen shot. Can anyone suggest me to oversome this?

Thanks,

Prasad
