Initial stock upload with MAP by disconnecting ECC-EWM

[bhoomikaprakash]

Hi,

We are merging two plants (IM level managed to EWM level managed). Decentralized.

The business requirement is to upload stock in EWM without posting anything in ECC and posting 561 in ECC by passing price in "Amount in LC" and header/line item text in MIGO. This posting should generate a material document and not an inbound delivery.

In order to do so, we need to disconnect ECC and EWM to avoid postings either way out. I tried multiple config related changes but the only one worked was to remove the setup between plant/sloc and ERP warehouse (Enterprise structure --> Assignment --> LE --> Assign warehouse number to plant/storage location). But, I am afraid that touching the core configuration may lead to inconsistencies later on.

Is there a way this can be achieved? Any other configuration setup that allows this? The whole fiasco is because the version of SAP EWM uploads the stock with standard price and not MAP in ECC.

Regards

Hello,

As per the Narsimha's comment you can select the flag and load the inventory in EWM, which will increase the inventory only EWM and there will not be any communication to ECC.

If you need the inventory to be loaded in a storage location in ECC, which is EWM Managed location, then you can use the IDoc MBGMCR with the movement type of 561 and make sure the IDoc Segment E1BP2017_GM_HEAD_01, Field EXT_WMS = 2. In this case, it will directly post the inventory in the storage location and no inbound delivery is created though it is EWM Managed storage location.

Do you mean using a LSMW with the idoc method type? I am asking because there is a huge load of data. Can you please provide rough steps to achieve this?

[partheeban]

Yes, I think you can use LSMW to create multiple IDoc or if your team have any Data system / PIPO System to leverage and send the IDoc to SAP system.

Do you have any documentation on how this can be done? I have never tried this before. Also, is there a field in the idoc to pass the price and header text?

Hi bhoomikaprakash,

here is an approach that worked in my projects before:

1. Disconnect integration in ERP (table T320)
2. Load stock to ERP with the price you require
3. Load (same) stock to EWM w/o posting to ERP (/SCWM/ISU)
4. Re-connect integration in ERP
5. Do stock check in EWM to make sure stock figures are right

Alternatively, you could:

1. Load stock to EWM with posting to ERP (/SCWM/ISU), with integration to ERP being active
2. Change price in ERP using MR21 - you should check with your finance guys whether that gives you the correct stock values

Hi Andreas, I thought of the same approach as suggested by you. But I am not too confident on the repercussions of disconnection the integration and then putting it back as it is a live plant where the stock is moving. I am not sure what kind of glitches this will introduce at the stock table level.

Is this something you have already tried with a live plant?

Ok, that's new information - I assumed you are talking about an initial stock upload situation.

Then you are left with the option that requires MR21.

Yet another idea, which requires more technical effort:

• Configure the interface ERP-EWM in a way that a 561 movement triggers an inbound delivery for EWM (or use a custom movement type similar to 561)
• Post stock in ERP using one line per bin (basically the same data you would use for /SCWM/ISU)
• Implement BadIs on either side of the interface to transfer the bin information, e.g. in a custom text (that's what I have seen being used in similar situations)
• Receive inbound delivery and create putaway task in EWM using the data in the custom text
• If you need to "migrate" handling units you would need some packing step on the ERP side and corresponding settings in EWM to able to GR the HUs

You would obviously have to do some customizing in EWM to automate the process for your purposes. Most likely, it would be good idea to have a separate inbound delivery type and WPT - just to be able to keep track of the documents being created for that "migration task".

Hello,

If you want to upload stock just in EWM, you can use option donot post in ERP in ISU. This will just load inventory in EWM.

Hello, thanks for replying. I am aware about posting the stock only in EWM but the real problem is posting the stock in ECC. In order to post 561 with manual price push, I need to disconnect the ECC-EWM systems so that no data is sent to EWM and a material document is created instead of an inbound delivery.
