Batch characteristics

[Former Member]

Hi experts,

I am receiving 3 material (same material no) for which moisture content range is different and attached MIC which has reference of batch characteristics. How can I give 3 different specifications for moisture content range?

You can do this two ways.

But first you create the moisture characteristic with a range of 0 - 100% or whatever the widest possible values are for your test. Then link it with your MIC.

1) Then you create three classes.  One for each different spec.  In the class you define the individual specs, like 4.0 - 5.0%, 3.5 - 4.25% and 2.0 - 2.2%.  In the class make sure you click on "Additional values" to allow recording of out of spec results. 

Now assign the applicable materials to the proper class.

Create one plan and assign to all materials/plants that are applicable.

Set up your inspection type(s) to inspect with task list and material spec.

Run transaction of QA61 to create the material spec for each material.  Just run it and save, you don't have to do anything else.

Create your lot, spec should come in.

Option 2.  Same as above but create ONE class only.  Then in the classification view in the material master for each material, you maintain the spec directly in the material master classification view.

Let me know if you have any problems.

Thanks FF…Some other doubts reg the same,

1.       1. In case, we are receiving single material in three grades, each grade has different attributes & specifications. Then how can handle this in order to maintain inspection plan & batch class?

2.       2. In certain point, need to change the specification of reference characteristics in the inspection plan, but its tolerance fields are greyed out? & changes made in class characteristics reflected in material master but not in inspection plan?

3.       3. What is the impact of cancelling (unlock master charac) the reference of class characteristics in the inspection plan?

Hi

If it is batch managed, you can have different grades for each batch of the same material with single characteristics as you can enter the exact moisture content for each of the batches.

1) If the material has three different specs, it's three different materials in the SAP world.  We don't really have a concept of grades of a material in SAP.  You can regrade materials from one material to another material number, and if you make materials using 03 lots you can receive to different batches based on quality, but you don't have grades within a material.

2) you don't make changes to the characteristic in the inspection plan. you make them to the spec contained in the class, or if you use option two, in the classification view of the material master.  In the inspection plan the fields should be greyed out as the spec value comes from the class values or the material classification value in the scenario I described.  The specs get copied into the inspection LOT at the time of creation. 

3) If you unlock the master characteristic in the plan, it loses connection to the specs in the class and material master.  You can do this and still upload the result to the batch.  The downside is that you must maintain the spec in the plan.  Which if you can normally assign multiple materials to a plan, (as in your case of grades of a product), you must now either create multiple inspection plans, (one for each spec), or use independent spec in the inspection plan.  By maintaining specs in the class,  you change the value once in the class and it cascades down to all materials that use that class.
