Transfer Posting without clearing not possible error while posting vendor down payment with Sp Indicator A

Dear Experts,

We have activated cash ledger in our system. There is  a scenario of Vendor Down payment. We are using standard Special GL Indicator A for Vendor Down Payment.

While Posting Down Payment through F-48 we are getting an error Transfer Posting without clearing are not allowed Message no. FAGL_CL051. If we use  Withholding tax code while posting then it allows posting but it deducts TDS against the payment. However, in our scenario withholding tax is not applicable. So, please advice how to ressolve this issue, request an urgent reply.
