Rule Based Availability Check --GATP

[Former Member]

From: Shashikant

Rule Based Availability Check:

Objective:
To carry out Rule Based Availability Check considering Location substitution with 2 plants - A and B

Following are the steps which are done:

1. Field Catlog with Sales Organization, Plant and Sold to Party
2. Condition table (501,502,503,504) used in the rule-based ATP check
3. Access Sequence( LOC1) determining which
   condition tables are used to access the condition records.  these condition tables which field contents (Sales
   Organization, Plant and Sold to Party)
4. Maintained the condition type( LOC1) and assign
   it to an access sequence(LOC1).
5. Maintained the rule strategy (Inclusive) which determines
   the condition types and defines the sequence in which they are evaluated.
6. Assign Rule Strategy (OMA)

            In this activity, you determine the
following activation parameters to determine the rule strategy:

• Technical scenario

• Business transaction

• Action type

7.  Rule  Maintenance.

• 
    Maintain Rules (4855_APOC)

       Inclusive,No restrictions, Substitution (Location Product)

• Defining the Location Determination Procedure (4855_APOC)

For the location determination procedure,
we have defined a list of locations (A and B). During the availability check,
SAP APO takes all listed locations into account. If the requirement cannot be
fulfilled in the original location (A), it is substituted by one of the
alternative location(B).

• Defining the Rules Control(4855): Location Determination
  start from top.

Access strategy of the substitution list :

1. Location: 01 Start from top of list
2. Str. Chars: Only use input values.
3. Restriction : Quantified Product & Quantified
   Location: No Restriction
4. Combine quantified product with all locations
   then quantified Loc. with all Product –ACTIVE
5. Combination: Union.

8. Creating Condition type link to condition tables
for Plant A and  B with { Sales Organization,
Plant Sold to Party } and RULE DEETERMINATION

         Problem :
After completion of above process when I created Sales order and click Availability
check icon the screen moves to APO  refer attachment without confirmation of available Qty from Plant A and alternatively
from Plant B.

If we click Check instruction--- Check Mode and Business
Event combination screen is displayed having RBA activated

If we click Rule –Rule evaluation – click start evaluation
--- the 2 Plant A and B are displayed.

If we click Rule Determination – Rule strategy sequence link
access sequence link condition table.

Final conclusion is that Result for RBA output not displayed.

Hi,

for me it seems that no substitution is found during the ATP check. The root cause can just be found via debugging as the setup seems to be fine. I can just recommend to raise a message at SAP to get a detailed analysis. sorry.

best regards,
