Problem with CAPP Transaction code

Dear All,

We are upgrading 4.6c to ECC 6.0 and now we are in UAT phase.

We have one Z program for approving time sheets and in that program we are calling "CAPP" transaction code through call transaction statement with mode 'E'.

After executing that report we are getting the output in ALV List format and we are unable to resize the columns and hide the columns,but if I try to execute the CAPP t.code directly i could able to get the output in ALV grid,and in that we are able to resize the columns and hide the columns etc. But before upgrade we were able to get the output in Grid display even after calling the t.code in the program.

My question is why it is not displaying in Grid display after upgrade?Does anything affected by upgrade?

Waiting for your replies...

Thanks & Regards,

Raju
