Hi
,
If for the particular material credit check is not required, you can do it with Item category.
Create a Item Cat group, Assign that to the mat required.
Create a new Item Category , Configure the Item cat determination using the above item cat group.
In the Item Category make the Credit active field unchecked. the your issue will be resolved.
Generally this process is used for slow moving products to promote sales .
