Dear Luk
thanks for your explanations. As mentioned: I haven't had the chance to deal with EHS / QM interface in reality; it is more based on analysis of the interface.
Let's come back to your topics:
* based on the ingredients, we want to check for content, how much of the chemical is present in the material
=> this type of analysis is done often; there are different levels of interest: e.g.
a.) you can be interested in the amount of water in the material
b.) you are interested in the amount of lead 2+, chrome 6+ etc. i
c:) you are interested in total amount of phospor, nitrogen etc. (this is sometimes called "summerized value")
Not all of that is maintained in EHS in VATs of type "C"; sometimes "A" is used.
But let us asssume it would be a VAT of type C and we have a spec id "X" saying that there is lead with 10 ppm, => I stilöl have doubt that there is a conversion possible for that in QM interface. You need to convert the e.g. "identifier" to a phrase related to a characteristic and you need a second characteristic to deal with the amount
Am am sorry. I do not have any experience in SAP QM. But is clear that it would be a great help to get data from EHS into the QM plan; as mentioned; I have some doubts about the QM interface. According to my understanding you need to maintain may plants as validity areas (as the QM plan ist pant oriented) You can not specify like "PUBLIC / REG_WORLD" and the value is valid for any plan
My proposal would still be to use one of the available "user exits" to get the demand done. The main "issues" is the "mapping" and conversion in any case.
E..g let's assume simple example. In QM you would like to test density, flashpoint, viscosity. Now EHS uses a number of characteristic to deal with that.
First step could be that you define per "VAT" a "default usahge (e.g. PUBLIC / REG_WOLRD); to read the data; now if more than one data record is present you get a "warning" et.c ( i have no idea how in QM three different values of density would be handled (tenmp: 15 °C , 20 °C etc.); Normally only one value is of interest. Now you can read the data and transfer it to QM plan.
How to deal with VAts of type "C"?. Here my suggesiotn would be: we need a "special" usage and a special data maintenance. E.g. we could define a rating "QM"; the in property "Standard composition" you would define one data record with "QM/RE_G_WORLD" Now by standard techniques you would read the data record. Now you need a "mapping" algorithm. One "stupid idea could be:
read iv there is average, min, max value; read form spec id used on identifier; now create a new phrase on the fly and use this phrase to populate the characteristic as part of QM plan.#
E.G. you have defined a value like:
Average Min Max UOM Spec ID
10 5 15 Mass% X (represint e.g. "Water")
Now you could (as with DG) generate a phrase like:
"Min 5, Average 10; Max 15 % of water " and populate the characteristic with this phrase
Now you have a "value" which could be checked in QM
Hope you will find a solution
C.B.
