Unable to modify the distribution lines

Hi,

I have made some manual changes to AP invoice header amount and AP invoice lines amount, but unable to modify the amount in case of distributions. There is a mismatch in case of distribution lines and header/lines amount and hence a hold is placed when validation was done. Current status of the Invoice is "Needs Revalidation".

On distributions page, everything is greyed out. Please suggest how can we modify the distribution lines, so that we can remove the hold and proceed with the validation of the Invoice.

This is not something related to the responsibility.

Please suggest.

Oracle version is 12.1.3
