Hello Panjat,
I notice that you are still using BEx Broadcaster 3.x
There are several correction notes about this class. Maybe one is valid for your current system version:
| 1477437 | Broadcasting of Web Template with Dropdown View dumps |
| 1972341 | 3.x Broadcaster setting without line breaks for text content |
| 1027119 | Suppressing footer: E-mail text is not inserted |
| 899861 | Broadcasting fails with an error DB_SAVE_LOG-01- |
| 885318 | Broadcasting w/ variant: Short dump STRING_OFFSET_TOO_LARGE |
| 792105 | Terminat. of prelim. calc. WebTemplate with many variables |
| 734584 | Incorrect link generation in broadcasting |
SAP currently only support BEx Broadcaster 7.0 (that one executed on BI Java Portal).
There, CSV should work.
More details about that, check this wiki:
