SUT selection in TO from storage type to PSA

[shankar_kumar]

Hi All,

The business process is Kanban replenishment where the CCID is scanned for TR creation for demand. TR then automatically converting to TO (movement type- 350). In TO we are getting the storage Unit type selected. need to know the basis of storage unit type selection.

Further details of the movement as eg.

Movement is from storage Type 030 to PSA.

Storage Type 030 has Bulk as Put away strategy and FiFo as Removal Strategy.

It is SUT check active.

warehouse is HU and SU managed.

Two kinds of SUT is there in the storage type 030 - Box and Pallet (L).

Let me know the basis of SUT selection in above TO.

The issue is that different material selects different SUT and there is no consistency. I checked for GR date, Quants, and material master, Move,ment Type data.

Need help from all experts.

Thanks,

Shankar Kumar

Hi Shankar,

As per standard SAP flow,

Step 1 ) system picks the stock removal indicator from the WM1 view of material master

Step 2) Picks the storage type from the T334T table based on the removal indicator from step1

Step 3) Once the storage type selected it goes and check the available Quant in the storage type

Step 4) After selection of all the Quant it sorts the selected record based on the GR date

Step 5) Once the first quant selected it pass all the Quant information to internal table

Step 6) Checks the required quantity minus quantity of first quant selected if the balance is greater then zero process continue from step 2 till the time required quantity - allocated quantity =0

Now your query how system selects the Storage unit type, as you can see from above steps system selects the  Quant and the quant is already having the Storage unit type assigned. in the below example i have four quant in the stock and my requirement is for 120 PC, you can see the Sequence in Transfer order system stamps the TO line item based on the Storage type search (003,002 in below case) and then based on ascending order of Goods receipt  it selects the Quant from within the Storage unit

in the below example

Storage type search strategy (Entry into T334T)

Stock in warehouse

Correct way is to define SUT in descending order by qty, e.g.
500 PC IP
300 PC EUR

60 PC BOX

If you are receiving 900 pcs, if you only enter 900 pcs in MIGO without specifying specific quantity split, the system will do the following:
1) First step: the system has 900 pcs to place, checks first SUT, 900 > 500 so it selects 1st SUT,
result - 1 IP is created with 500 pcs.

2) Now we have remaining 400 pcs. The system checks first SUT - 400 < 500 so it skips IP and tries with the next SUT => EUR. 400 > 300 so it selects EUR, resulting with creation of 1 EUR with 300 pcs.
Now we have 2 storage units, 1 IP with 500 pcs, and 1 EUR with 300 pcs.

3) We have remaining 100 pcs. The system checks first SUT - 100 < 500, skips to second but 100 < 300 too, so it skips to last SUT and selects it since we have no more choices - resulting in creation of 1 BOX with 60 pcs. We have 40 pcs left.

4) Again the same as number 3) but we only have 40 pcs left. We have another BOX created with 40 pcs.
So the result for 900 pcs would be:
*  1 IP with 500 pcs
+ 1 EUR with 300 pcs
+ 1 BOX with 60 pcs

+ 1 BOX with 40 pcs

Hi Mihailo,

In the business scenario, while removing the material from storage type, We get SUT selected in the TO. We have stock of both type of material (BOX and Pallet) in the storage Bin.

Not able to know, from where it is getting selected.

in this case

300      PC         Pallet (L)

60      PC           BOX

we have TR of 60 pcs

Stock is of 120 Pcs of Box and 300 Pcs of Pallet.

when this TR converts to TO, in some material it takes Box and sometime as pallet. Requirement is to remove only Boxes from this storage type.

Hi

at the time of TO creation SUT selection happens from the master data you define in the WM2 view of the material master for the material

[shankar_kumar]

In this case we have two SUT in material master data.

L and Box. and stock is of both the material.

material master palletisation data is as -

400 PCE L

50   PCE BOX

Hi

As per the FIFO search strategy system first check the storage type and then cheks the possible assignment of storage bin type and storage unit type from the Storage bin type search strategy and based on that it decide the SUT.

If you want to know more in detail in then pass me the screenshot of your TO along with your material master and Storage bin type assignment detail and i will forward the exact logic
