Error while generating screens in BDT

Hi All,

I getting following error while generating screens using t-code BUSP for a CAA2 t-code

-

"Client 040 appl.object REWB screen REWB10:Error during subscreen container gener

Message no. R11520

Diagnosis

Errors have occurred during screen generation. The reasons for this could be:

The maximum length of the screen was exceeded. There may be no more than 199 lines per subscreen container.

The maximum number of lines for the header-data area was exceeded. There may be no more than 15 lines in the header-data section.

Procedure

Check both of these potential sources of errors in the relevant screen, and make the necessary changes.

with regards,
