URGENT-IS RETAIL- SCANNING USING HANDLING UNIT (T.Code HUPAST)

Hi,
Can any body please let me know urgently the total configuration for Hupast in IS Retail. Will a functional person be able to do all the configuration? The requirement is system should be able to generate HU against the outbound/inbound delivery as we enter the packaging type in Handling Unit field (in T.Code Hupast). Then the stocks will be scanned against this HU with reference to the inbound/outbound delivery no. And PGI/PGR will be done using the HU no. Many retailers use this T.Code HUPAST. I have followed the functional specifications from "G74 - Handling Unit Management" from help.sap but still as I enter the packaging type in HU field the system is unable to generate the HU no.
I will definitely reward points to the answers that will solve the purpose. Please give all the config steps.
This is really very urgent.
Thanks
Anirban

Did you ever get an answer for this? We would like to backflush some HU managed materials as well.

Program code and transaction code for handling unit detail

Developed a SAP Script for the Handling unit details. Handling unit details is a document which has the details of materials, packaging materials and the level of packing. This Handling Units details will be issued to the customer at the time of delivery.

Hi,
Goto NACE transaction code , there you select the application area then it will give you the list of output types then select specific output click processing routines then you will see the program name and script used.
Or esle goto SPRO tcode then you can find the functional tab there also you can get the details.
Thanks,
Aditya

Do we have any standard T Code to list out all deleted Handling Units?

Create and Pack Handling Units in the Sales Order Using HU_CREATE_ONE_HU

Hello Experts,
I am trying to use HU_CREATE_ONE_HU function module to create a handling unit and pack it with specific line items in the sales order program in the background. I am able to create the handling unit and pack it but it does not get associated to the sales order / line item. If you look at the sale order's packing proposal, it does not show it packed. If I look at VEKP / VEPO, I see where it was created but there is no value for vbeln or the posnr I proposed. Below is the code, I am using. Does anyone know what I am doing wrong or is there another function module I can use?

The abap statement does not make sense.
xlips_high_posnr = ( lips-posnr / tvlk-incpo ) * tvlk-incpo
posnr & incpo are both type numc length 6.
Here is my recommendation to catch the divide by zero error.
data: l_oref    type REF to cx_root.
data: l_text    type string.
TRY.
        clear l_text.
         xlips_high_posnr = lips-posnr / tvlk-incpo.
        CATCH cx_sy_zerodivide INTO v_oref.
          l_text = l_oref->get_text( ).
        CLEANUP.
*      Put your code to do further processing if it is divide by zero
ENDTRY.

How to unassign handling unit in outbound delivery?

(Don't Want to delete HU onlu unassign it from delivery: WM requirement)
I would like to unassign HU in an outbound delivery.
code i'm using make the handling unit disappear in the overview of HU.
but corresponding line in the "item overview" are still existing.
And when I want to copy pack quantities as delivery quantities, system tell me that "50.000 M have already been packed. Quantity cannot be changed. "
How can I do, to do as if i pushed button "delete assignment" in HU overview?
Here the code I'm using:
CALL FUNCTION 'HU_PACKING_REFRESH'.
CALL FUNCTION 'HU_GET_HUS'
EXPORTING
if_lock_hus = 'X'
it_venum = I_VENUM "it_venum contains l_venum
IMPORTING

IMPORTING
ET_NEW_HUS = LT_HUS
et_messages = lt_messages
EXCEPTIONS
FATAL_ERROR = 01 .
CALL FUNCTION 'HU_POST' .
call function 'BAPI_TRANSACTION_COMMIT'.
Please let me know the function module if anybody has idea to unassign from delivery.

Outbound Delivery Handling Unit HU material box pallet

Business requirement.
To create a delivery based on a sales order using a function module. To do this, users have an AbapWebdynpro application to collect data,
Handling units for boxes and handling units for pallets are creates as the user packs his materials in the application.
Items are packed in boxes and boxes on pallets.
Problem description: cannot pack boxes onto pallets.
I can pack items in boxes no problems. Delivery gets created ok.
How i do it:
Step 1:
At the end of AbapWebdynpro process and validations, if no errors occurs, a function module is called to format the data and call fm to create a delivery.
This part works as expected and is all ok.
Step 2:
Then in the function module that will create de delivery, header proposal is filled for boxes and pallets. itemproposal is filled for items in boxes and pallets
Step 3:
then,
FUNCTION 'BAPI_HU_CREATE' is used to create handling units for items
This part works perfectly for boxes and items but not for pallets.
then, delivery create
CALL FUNCTION 'SD_DELIVERY_UPDATE_PACKING_1'
EXPORTING
delivery = ls_createditems-document_numb
commit = 'X'
synchron = 'X'
TABLES
verko_tab = i_verko
verpo_tab = i_verpo
prot = i_prot
it_handling_units_1 = i_handling_unit
EXCEPTIONS
update_not_possible = 1
OTHERS = 2.
This part works fine also if not pallets HU are present in the data .
The problem is when i want to create a pallet and add the boxes to it. I have tried about every thing i read but had not much success.
The only thing that came close to doing the job is the following code.
First i create the delivery with boxes and materials only and with the following FM, i create the pallet and attach it to the delivery line but then i can not assign the boxes to it.
ls_handling_units-top_hu_external = ls_packed_pallets-hu_pallet.
ls_handling_units-top_hu_internal = ls_hupallet.
ls_handling_units-venum = ls_huboxes.
ls_handling_units-vepos = ls_packed_boxes-posnr.
ls_handling_units-rfbel = lv_vbeln.
ls_handling_units-rfpos = ls_packed_boxes-posnr.
APPEND ls_handling_units TO lt_rehang.
Step 4:
CALL FUNCTION 'SD_DELIVERY_UPDATE_PACKING_1'
EXPORTING
delivery = ls_createditems-document_numb
commit = 'X'
synchron = 'X'
TABLES
verko_tab = i_verko
verpo_tab = i_verpo
prot = i_prot
it_handling_units_1 = i_handling_unit
EXCEPTIONS
update_not_possible = 1
OTHERS = 2.
Is anyone succeed to create a program to create outbound delivery where materials are pack into boxes and those boxes are packed on pallets.
Regards
dstj

If the delivery document PGIed then you need to do VL09 transaction to reverse the PGI document.
Then do in VL02N transaction select Delete handling unit assignment icon it will remove all the handling units from delivery.
Later goto EDIT option then selct copy pack qty as dlv qty then save.Later system will allow you to delete the document.

Handling Unit not being assigned to TO for an outbound delivery

Hi All
When I create a TO for an outbound delivery then a handling unit is not being assigned to the TO.
I cannot confirm the TO as it complains about the non assignment of HU.
I have done the following so far:
1. Set up a default packing material w.r.t WhNo and movement type.
2. Defined a packing group and then assigned the packing group to the packing material.
3. Set 1 to the indicator for automatic HU creaion in customizations for automatic HU creation.
Is there something I am missing in the configuration?
Any suggestions would help.
Thanks,
Arup

Hello,
HU never get assign at the time of creation of TO. You can assign pick HU at the time of confirmation of TO. There are two ways
Use transaction code LH01 and assign pick HU
OR
(ii)Or at the time of confirmation of TO click on pack tab and complete the packing
Thanks,

Handling Unit creation

Dear Friends,
I am able to create the Handling Units using BAPI_HU_CREATE but not able to assign the HU to delivery.
I can see the HUs are created in VEKP tables correctly.
I am using the FM 'HU_ASSIGN_HUS_TO_OBJECT' to assign this to delivery ( LIKP-VBELN ).
See the code below, in debugging all the values gets filled correctly including lt_hu_units but HUs are not assigned.
I can not see those later on in VL02 & then clicking on Pack from menu bar.
Not sure why the below FM not working correctly?
Pls. see portion of code below for your referance:
    ls_hu_units-top_hu_external = lv_hukey.
    ls_hu_units-venum              = ls_huheader-hu_id.
    ls_hu_units-rfbel                 = gs_header_details-vbeln.
    ls_hu_units-rfpos                = 10.
    APPEND ls_hu_units TO lt_hu_units.
    ls_object-object = 01.
    ls_object-objkey = gs_header_details-vbeln.
    CALL FUNCTION 'HU_ASSIGN_HUS_TO_OBJECT'
        EXPORTING
          is_object                 = ls_object

Hi David.
There are two areas for creating packing instructions
Packing instructions and then packing instruction determination
Transaction POF1 and POP1 (Cannot remember which is which)
You will need materials set up to represent packing items such as pallets etc, and these are then included in the packing instruction.
Config in HUM will allow you change the level of determination, plant etc
Good luck

Handling Units Deletion from Shipment

Hi,
I got a problem in deletion of handling units using the FMs V51P_FILL_GT and then HU_PACKING_AND_UNPACKING. The FM HU_PACKING_AND_UNPACKING has got a structure gt_xvekp which gets populated dynamically when a HU is deleted from a shipment, but this is not happening when i call the FM separately in a program. Can any one help me or provide me a sample code in resolving this. Correct answers would be rewarded.
Thanks
Abhishek

Hi,
LT06 is to create TO with reference to material document.
I'm not sure what you want exactly. You marked creation of TR in customizing - in this case you have to create TO from LB10 from the automatically generated TR or you can create TO automatically with suitable reports (you have to run programs in background).

http://help.sap.com/saphelp_erp60_sp/helpdata/en/c6/f8406c4afa11d182b90000e829fbfe/frameset.htm
If you want to have immediate TO (you want to create the TO at immediately after GR si posted), you have to set it in customizing in WM-IM interface. Please read OSS note 566090 for details.
Please also search on the net / forum.

Hi Sailaja,
I have similar requirements like this before with HU_PACKING_AND_UNPACKING FM. It was a tough debugging before I came up with the right solution. Unfortunately, I was not able to document that code..
But here is what I have been doing.
Youre on track with the solution below, never use BDC as it will only limit the Handling units that you wish to put into.
The function modules that starts with V5_ plays important role as you need to initialize the global variables and table of this function group with values before calling HU_PACKING_AND_UNPACKING FM
Debug inside the Function module, and look for the FM that returns SY-SUBRC <> 0 then set a breakpoint.
Restart the program then debug inside that FM again (and I do not want to go further on the details, I give you the presumption of literacy)
You will find some items that has no value, try to initialize everything by utilizing the FM for this function group V51S.
Happy Debugging.

External Handling Unit (Barcode) Information is Missing

Hello Folks,
I got a requirement where a warehouse will send us an EDI 945 file to confirm the shipment completion. But, it send us the file without SSCC labels for those shipped items of the order. This 945 is being translated into a SHPCON IDOC(DELVRY03) which doesn't contain the E1EDL37(Handling unit header). This IDOC is failing in status 51 with the error message: External Handling Unit (Barcode) Information is Missing.
What should be done to get this IDOC posted sucessfully even if it doesn't contain the SSCC label? Is there any setting that should be changed for this customer to not to look for SSCC labels(External Handling unit).
Thanks for your help,
Siva

This could be because of custom code. Check the exits in inbound FM and you should find out the root cause. Standard SAP doesn't check for customer level SSCC checks. If it gets the HU's from 3PL, it'll pack it such way. If it doesn't, it'll pack is the usual way.

Handling unit process step by step

Dear All,
We intend to use handling unit functionality.
Our FG let's say FG001 gets packed in container.
I have mapped this as following.
I have created 'Container' as code with material type VERP- Packaging Material. Maintained the required data in Sales org. tab page.
I have created packing instruction in POP1 with container as packing material & FG001 as material.
I have maintained the determination record in POF1 (Frankly I didn't understand the relevance of this step, but did cos has been suggested in several threads.)
Now I have to perform the packing process of FG001 in HU02.
But system is throwing me an error as 'No packing instruction could be found for material FG001', message no. VHUPD002.
I have stuck up there. Kind request you to help me in this, regarding any configuration & processing step, if I am missing.
Also I am few questions to get clear.
1. How to maintain the batch no. of packing material 'Container' while creating/ generating HU as my packing material is batch managed, and need to have information in which HU the batch of packing material is utilized.
2. What happens to the stock statement (MMBE)of both the materials i.e. FG001 & Container when those are get packed i.e. HU created/ generated.
Please respond urgently.
Timely answers will be rewarded.

VS,
Thanks once again.
You got it right. I was confused as I was unable to understand why packing material is not moving along with the FG material.
Moreover our packing material is container. Once it is packed container moves from plant to plant & then to final destination.
As we have to track the movement of the container, it was necessary for us to the have stock statement.
I am still surprised why standard SAP doesn't support the movement of the packing material along with the contents i.e. FG?
Now to tackle this, we have thought of a way out.
We have maintained two material codes for container. one is dummy container and second is main container for which we have to track the goods movement. Both will be having same material type as VERP but only difference is later won't be having packing material type in sales view. So it will act as normal material.
While creating HU with HU02, both the materials with quantities will be entered in pack material section. Dummy packing material serve as packing material. Here my question is what is HU creation & HU generation? Because system is throwing me an error while generation as 'no packing instruction are there for the material although I have defined determination source in POF1 but when I save the HU with out generating it, system doesn't throw this error
The HU is getting created but I am unable to enter that HU number in VL01N while creating the delivery. How to do that?

Handling unit delivery reversal with VL09 in ECC 6.0

Dear All,
We have created few deliveries which has handling unit & packing. However now these deliveries are to be reversed or cancel due to the adress change.
These deliveries are created when we had 4.7 version but this month we upgraded the system to ECC 6.0. Now when I am trying to cancel delivery with VL09 transaction code system is popping the error up as "HU items' material posting is inconsistent".
I came to know that there is some change in standard process of handling deliveries in SAP 4.7 & ECC 6.0. I just would like to have details of it.
Regards,

Hi,
What kind of deliveries are you handling? Deliveries for sales order or for Stock transport orders?
Note 992460 - VL09 fails with error message HUGENERAL 327 describes the symptoms but seems to be valid only for IS Retail systems.
What's the status of HU saying? Check HU numbers in outboud delivery for that.

Handling Unit Link (VEKP-EXIDV) in inbound/outbound delivery

Hello,
I need to code the automation of logical pick and pack tasks in the trading company such that the following fields of the outbound delivery are automatically populated based on the corresponding fields from the inbound delivery:
1.) Pick Quantity (LIPSD-PIKMG) comes from the pick quantity from inbound delivery to trading company
2.) Batch Number (LIPS-CHARG) comes from the batch from inbound delivery to trading company
3.) Handling Units (VEKP-EXIDV) comes from the handling units from the inbound delivery to trading company.
I've found a way to link the outbound to it's corresponding inbound delivery through table EKES (link of stock transfer order number to the inbound delivery), however I could not find the link of the stock transfer order to the handling units (VEKP-EXIDV).
Any idea on this?
Thanks.
Sincerely,
Ice

//What I found was that VBFA-VBELN = VEKP-VENUM, given that VBFA-VEBELV = inbound directory (LIKP-VBELN) and VBFA-VBTYP_N = 'X' (handling unit).
From that link I was able to get the external handling units (VEKP-EXIDV) since the key VENUM has been identified.
During the pick and pack i have to link the LIKP+LIPS and VEKP for handling unit and internal identification number.
VBFA is for sales document flow which is helpful for forward and reverse navigation to itdentify the documents .
Inputs for the Feed has to be from LIKP / LIPS and VEKP
Please refer to tcode VL02N and in here check Packing options with all the subscreens of Packing Hu's and Single entry .
regards,
