Hi everyone,

We are exploring the use of ERUs in CU3 and from Oracle Open World conference slides, there was a mention of being able to plan mixed ERUs.

I have tried a simple example of the following - but it does not work!

1) Consolidation of 2 Orders with different ERUs into 1 Shipment
2) 1 Order with 2 ship units each with different ERUs planning into 1 Shipment

I am unable to get OTM to plan the above scenarios into 1 shipment

Has anyone ever used ERUs? Any ideas on when ERU should/should not be used?

Thanks for any help!

Hi Ian,

We are succesfully using mixed ERU's for your scenario nr 2), but I would say that 1) should work as well.

A few things to consider:
- Planning Parameter CHECK EQUIPMENT CAPACITY IN REFERENCE UNITS should be set to true
- The combined volume of your ship units should not be more than eqmt capacity. Same for combined weight. ERU's are only meant to restrict within the limits of eqmt capacity.

Our set-up is as follows. ERU ABC has X number of ref units against a 40 High Cube container. ERU DEF has Y number of ref units against a 40 HC. ERU ABC has a count of 1 against Ship Unit Spec abc. ERU DEF has a count of 1 against Ship Unit Spec def. During planning the following calculation is performed.
(((Ship Unit Count for SU Spec abc * 1) / X) + (Ship Unit Count for SU Spec def * 1) / Y))) <= 1
If indeed <=1 it will build into single shipment.

Hope this explains.

Hi Rob,

Great! Thanks for the help! Just a follow on question. Are you able to build multiple equipments within 1 shipment with your model?

Hi Ian,

We're working on a model with 1 eqmt per shipment, so don't know whether it works for multi eqmt shipments. Give it a try and let me know...

HI Ian,

Shipment can be build with multiple equipment in it .

Make sure you check create single shipment in the itinerary and dont check the Container option in the equipment type .

Hi Rob,

I tried your recommendations but I was not able to build a consolidated shipment. It always gives me 2 shipments instead of 1.

I checked the logs and here's what it says:

2008-02-22 16:38:13.198 517220 Debug Conopt Check equipment capacity in equipment reference units: true [batch - 1]

.....

After looking down the log, I find another piece of information:

2008-02-22 16:38:13.202 517220 Debug BulkPlanning Order movement bundle |DEV/CHN/WGQ.IL_2008_TEST_01-003-001|DEV/CHN/WGQ.IL_2008_TEST_02-003-001| failed to build shipments. [batch - 1]

2008-02-22 16:38:13.202 517220 Debug OrderBundling Begin BaseOrderBundle::constructor... [batch - 1]

So apparently, after the shipment fails to build, OTM then tries to replan without consolidation.

Is there any other configuration / setting that I may be missing?

Appreciate your kind help!

Hi Kishore,

Yep I did the same. But was still not able to build it. I am using 5.5 CU3 RU1

Hi everyone,

I tried to build a shipment from an order with 2 different ERUs (making sure that the order can fit in to the equipment). However, I get a failed plan with the following error:

2008-02-22 17:00:18.285 649762 Debug Conopt Check equipment capacity in equipment reference units: true [batch - 1]
2008-02-22 17:00:18.286 649762 Error Exception Different equipment reference units DEV/CHN/SHARED.ERU_150_150 and DEV/CHN/SHARED.ERU_120_100 are defined for package lines.

Appreciate if anyone can kindly help explain why this error is happenning.

Attached is the log file for the planning session in error.

Thanks for all your help!

Hi Ian,

We're not using Order Movements so can't say whether they are supported or not. Furthermore it seems that ERU's are not compatible with the Legacy CONOPT algorithm, so try with quick packing or single / multi container mip.

And our ship unit specs are set-up with a unit type of 'both', maybe that influences as well.

[krishna.kk]

Please ensure that BOTH the splittable check box on the Order Release tab and also the Bulk Splittable flag on the Ship Unit pag
e is both checked and then do a fresh bulk plan and let us know .

Hope the weight or volume of the order release is more then the weight of the equipment capacity defined only then it will create single shipment with multiple equipment.
