Issue with zero credit limit in customer site level

Hi

Zero credit limit in bill to site level causing an issue while placing order. Order getting failed due to credit check failure.

we observed it's happening for newly created customer, is there any script or API to remove the zero credit limit from site level and make it as null, in order to avoid credit check failure.

seems most of the customer having the same issue with zero credit limit at site level. Each and every time we request customer master team to remove the zero from site level. It would be better if we have some script to make the change.
