Tax G/L account error in invoice

Hi friends,

We have two scenario ie sales from DC(distribution center) and sales from MFG plant. the tax G/L account are different for both but after analysis in FTXP and OB40 for our tax procedure I found the G/L account for MFG plant only.

I am not able to track that what is the source for DC tax G/L account.

what are the different sources where we can define the tax G/L account.? is there can be diffrent source for DC G/L account.

regards
