Cannot remove the SPL block against delivery

Hi Team,

I found delivery with transaction /SAPSLL/SPL_BLCD is showing in blocked list. I checked customer is in boycot list but that customer has been deleted from table /SAPSLL/PNTBP & BUT000. During manual SPL release for documents it states u201Cerror when posting auditu201D. How to rlease the block.

Thanks

Sits.
