Problem in SD invoicing

Hello,

I am facing problem while releasing document from VF02 transaction. For a particular G/L account it says Account &1 &2 defined for tax postings only (msg class: >0 msg number: 123). This error comes from function module FKK_MWSKZ_HKONT_CHECK

When we change some customizing in SKB1 table then it gives error as u201CAccount &1 &2 not defined for tax postingsu201D ((msg class: >0 msg number: 124)

I changed Tax category to u2018+u2019 and Relevant to cash flow = u2018Xu2019 in table SKB1 in transaction FS00.

Could you please suggest some solution to remove this error.

Thanks and regards,

Minal Nigade
