Purchase order user Exit

[former_member125661]

Hi guys,

I have a case where I am modifying the quantity on a purchase order line item in Me22 or me22n.If this PO is tied to a nomination, I dont want the order quantity to be changed. Suppose I have Order quantity of 200 KG on item 10 and if item 10 is tied to nomination and if i try to change it to say 150 kg, I want my user exit to change it back to 200 KG when i click on save. So, I put my logic in an include file in EXIT_SAPMM06E_013 . Basically, I am trying to copy YEKPO-MENGE back to XEKPO-MENGE. But this doesn't seem to work. My quantity is still saved with 150 KG when i desire to have it unchanged as 200 KG. Here is the code below. Am i using the right user exit and the right Communication structure ? I am not sure if XEKPO and YEKPO are the ones I should look for. I even tried XEKET and YEKET. Did not work .Any help to solve this issue is greatly appreciated!

Try include program ZXM06U43. This is an include in User Exit EXIT_SAPMM06E_012. This gets triggered when you save a Purchase Order. Here you can modify PO Qty. You will have to populate PO Item details from EKPO and modify internal table which contains PO Items details (after user modification).

To use this exit, you can do like this:

1. Run transaction CMOD.

2. Enter a project name. Create your own name. Check with your company naming range for user exit name.

3. Click on enhancement assignment

4. Select MM06E005

5. Doubleclick on EXIT_SAPMM06E_012

6. Doubleclick on include ZXM06U43

7. Inside this include you can start doing your Abap. Check on the fields you want to compare. And then you can modify data accordingly.

I will try that Ashish. I have a quick question. Do i always have to create a project in CMOD ? Can I not open ZXM06U43 in se38 and add my include file with logic there ?

Thanks

is any XEKPO and YEKPO structure avaiable in this user exit - EXIT_SAPMM06E_012 ? If yes, I will try to copy YEKPO-MENGE back to XEKPO-MENGE.

Hi Shareen,

You have to crate a project in CMOD. So that you can activate the enhancements you have done to the transaction.

I tried to use EXIT_SAPMM06E_012. It has a TEKPO internal table containing the new values. I replaced the Menge value here by the old value in EKPO-MENGE..But still the new value is saved Same thing happened in my exit above mentioned too. I was trying to copy the old value YEKPO-MENGE to XEKPO-MENGE, still the new one is getting saved , when i click on save.

[former_member125661]

Hi ashish,

I edit the fields of internal table TEKPO with whatever values, I need. But when saving, the PO is not getting updated with the desired values. Is this TEKPO getting refreshed or does it lose its scope when it comes out of the user exit ? Same is the problem with EXIT_SAPMM06E_013 too. I have both the old values and new values in YEKPO and XEKPO. I try to copy some fields of YEKPO to XEKPO..But somehow, its not getting updated.

THanks,

Hi Shareen,

In same EXIT_SAPMM06E_012, try to compare the old PO qty and changed PO qty if they are different then throw an error message. this stop the further processing of PO and will not allow user to save the changes.

then the original quantity will be retained.

Hi Rahul,

THis is what i am trying to avoid. I want the user not to change only the quantity field. All other changes he has made needs to be saved.So,I dont want to throw a hard error.

Hi Shareen,

According to my observation,

The User exits are provided for custom fields created on screen exit at header and item level, Quantity field is on standard screen. it has its own processors. custom sub screen can not control the process on standard screens. even if we try to assign data to standard fields at runtime, I found the value is lost in the execution and the chages doesn't reflect on screen.

Rahul,

I need to correct u. The Exit says Customer fields, not custom field 😛

rgds,

[former_member125661]

I tried Ashish. Did not work..I have access for both old and new values . But when i copy the old value to new values, it loses it scope after couple of exits.

The i thought EXIT_SAPMM06E_017 might be the best one to use. Even that did not work.

Thanks,

Shareen,

I am facing the same problem too. I have check the standard SAP code and found out that, whether you make changes to the data in the userexit for the EKKO, or EKPO, or EKET it doesn't reflect in the actual PO. Mainly all the PO userexits are there to show a custom error. The data which you can modify are only the customer (or custom) fields. I had to modify the delivery date for my requirement. What i did was modified the standard code by getting the object key? there is no other go, even checked with SAP.

Let me know if you need some help.

Dear Rajadeskhar,

None of the User exits your mentioned below. Most of them sound like they are for EDI.

I just want an user exit for Me22 or Me22n in 4.6 C which can alter certain fields like MENGE ( order quantity) during save, based on certain conditions,

Hi,

These exits are in <b>ECC 5.0</b>

Try this program to know all userexits for a given transaction.

<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/abap/abap-code-samples/userexits%20in%20a%20transaction.doc">Userexits for a given transaction</a>

I know about that program to find user exits given a Tcode. I know all the available user exits for me22 and me22n. I just dont know why the changed i make to XEKPO, or TEKPO or XEKET are not getting reflected ? is any other process over writing it ? I tried to use field symbols so that i can retain its scope outside my include program. Doesnt help . Distress. SOS

Hi guys,

We succeed in solving partially the problem of modifyng the PO quantity (menge) using the SMOD exit MDR10001.

In this case, the FM EXIT_SAPLMDR1_004 can be used to trigger a modification in CH_S_RESULTS-menge e CH_S_RESULTS-lmenge. This modification is copied back in the PO item.

The only problem is that if the PO item is created with quantity zero, this exit is not alled.

Let me know your feed-back
