GATP - Issue with substitution rules with validity dates

[Former Member]

Hi,

We are using GATP with RBA. Our condition table has plant as a field.

We are planning to have a substitution procedure (rules) defined at plant level.

Our rule control for product substitution list is "Start from top of list"

The issue we are facing is explained below.

The first item in the substitution procedure (rule) cannot have validity dates.

So it will always be balnk. And validity dates can be maintained for other items in the procedure (rule).

What happens in our scenario is when there is a requirement on an item in the substitution procedure (rule) which has a validity date, the first item in the procedure (which can never have validity dates) is never considerd for substituions.

If I remove the validity dates, then the first item in the procedure (rule) is considered for substitutions.

We find this strange and against our business requirement. We want the first item in the procedure (rule) to be considered for substitution ireespective of the validity date for the requested product.

It would be great if you could suggest a method to achieve this.

Thanks & regards,

Hi

What you're seeing is not the standard behavior. I'm sure there is not any relation between not having validity date for the first item and it's not being considered in the substitution. Before we think about other options to achieve what you want, may I know as to how did you infer that the first item was never considered? Have you tried Rule Evaluation directly in the Integrated Rule Maintenance? And also, are you using Rules Immediately in the check instructions?

Hi Mohan,

Thanks for the response.

We are using back order processing (BOP) for allocation.

We observed that the first item was not getting considered for substitution in the BOP results and also in product view after the BOP run. No stock of that item was allocated for the order taken up in the BOP run.

However, we tried rule evaluation also. It shows the first item also, but in actual allocation the issue exists.

We are not using "start immediately" in check instructions.

Thanks & regards,

Hi Arvind,

If you're asking about BOP specifically, you can check if you're using Rules Evaluation Again or not in the BOP processing parameters screen. If this check box is not checked, system will not evaluate the rules again, i.e., it confirms the product from the previously confirmed location product.
