WOCR and Wave Creation

[Former Member]

Hello Experts,

Need clarity on the below topic.

I know that WO is an optimum work package and is a bundle of WTs which are bundled using WOCR.

Now wave is the picking mechanism used to bundle the items in the ODO based on picking area or methods of picking.

1) is it ODR or ODO which is undergoing WOCR...?

2) is ODR creates ODO upon undergoing WOCR....?

3) on what basis is WAVES created...?

4) On what basis is the ODO items assigned to the WAVE...?

5) Can we create a WAVE before shipment...? If so then do route determination has a role to play in WAVE Creation.

6) What is the flow of WOCR and WAVE creation...?

7) What is the role HU in WAVE creation...?

6) If waves combining ODO items...are these items are again each each WT...? If its WTs then , WOCR and WAVE both are having the same functionality or what...?

Sorry to put all these Qns , but even after reading many posts i couldnt get a proper understanding of ODR->ODO_>OD flow with WAVE and WOCR.

Could you please help me in this. Thanks.

Thanks in advance.

Hi,

Not able to answer all your questions, but you should be able to find some more information here:

Wave - Wave Management - SAP Library

In short:

1. The ODR is basically a copy of the Outbound delivery from ECC. It is not involved in the whole WOCR / Wave process.
2. Based on the ODR, the ODO is created in EWM. Each ODO-item can be assigned to a specific Wave. It is possible to assign ODO-items from one ODO to different waves; you can also assign ODO-items from different ODO's to one Wave.
3. The Wave assignment process takes place before the WT's and WO's are created. Once you release the Wave, the system will create Warehouse Tasks. After the WT-creation, WOCR functionality is called to determine the correct Warehouse Order Creation logic.

Hello Oliver,

Thanks for your reply.

"The Wave assignment process takes place before the WT's and WO's are created. Once you release the Wave, the system will create Warehouse Tasks. After the WT-creation, WOCR functionality is called to determine the correct Warehouse Order Creation logic."

If this is the case then,

Once wave release happens , then this will create WTs, and then WOCR is called to create WO.

In this case the WAVE release is for the picking activity and for this picking activity there need to be a WO....right...?

If WOCR is set after the WAVE release then what about the "picking Activity" accountability...?

wont this come under WO.

Coul you please let me know the time based steps what happens first an the what happens for this WAVE and WOCR.

Hi M R,

"Once wave release happens , then this will create WTs, and then WOCR is called to create WO."

Correct, this is what happens.

"In this case the WAVE release is for the picking activity and for this picking activity there need to be a WO....right...?"

Not sure if I understand what you mean here... Once you release a wave, the system creates Warehouse Tasks for each item which was assigned to the wave. Next, the system will group the WT's into one or more Warehouse Orders, based on the rules which you defined (WOCR).

These Warehouse Orders are essentially your picking orders, which allow you to perform the actual picking process.

Hi,

maybe it helps not to read postings here, but the standard documentation first (although I agree that somethings it is hard to find logic in there)?

For example:

"4) On what basis is the ODO items assigned to the WAVE...?"

see this: Automatic Wave Assignment - Wave Management - SAP Library

Hello Juergen,

Thanks for your reply.

Could you please let me know the time based steps what happens first an the what happens next in perspective of the  WAVE ,WT, and WOCR.

Hi,

1. Warehouse request items get assigned to a wave.

2. The wave is released = WTs are created.

3. WOCRs are determined and WOs are created.
