DTP loading to master data is running long due to lock on SID table

Hi All,

 

We have DTP loading directly from infoobject to master data infobject. DTP usually takes less than 30min to update but at times its observed the DTP runs for hours to update. No dump was found on ST22. and no locks on sm12 apart from this DTP. On analysing the log in sm37, we found exclusive locks on the SID tables.

Is the lock on the SID table reason for the delay?? if so how to avoid this delay?

 

if not, What are the other possibilties to avoid this issue ??

 

Thanks in advance.
