Drawbacks of LIS compare to LO

Hi friends,

could u plz give me the drawbacks of LIS compare to LO Extraction.. and when we go for LO....

dis advantages in lis

only v1 and v2 jobs are possible

huge amount of data extraction even we want to extract specifiic level of info

advantages in lo

v3 job is avialable

specific level of info can be extracted.

Hi

Now a days no one is using LIS,,only LOs.

LO Supports V3 (Delta Mechanism)..LIS won't support..

Thanks

Why did SAP create LO (2LIS) extractors in the first place? What's the big plus here, because I haven't found it yet.

They are a pain in the @$$... You need to isolate the system to initialise them (try that in a huge 24/7 organisation), you need to empty Q's when you transport changes and if you don't your delta is messed up, which results in another setup which takes multiple hours (with a closed system again).

I'm in BW system maintenance in a very large 24/7 company and it's just very maintenace unfriendly. If only all delta mechanisms were a simple init/delta type like 0CO_OM_OPA_6.

hi

LIS is old technique through which we can load the data. Here we use typical delta and full up-loading techniques to get data from an logistics application, it uses V1 and V2 update, it means that it was a synchronous or asynchronous update from the application documents to LIS structures at the time when the application document was posted.

LO Cockpit is new technique i think from bw 3.0 ( i am not sure) which uses V3 which is an update that you can schedule, so it does not update at the time when you process the application documents, but it will be posted at a later stage.

Another big difference between LO and LIS is that,

You have separate datasources for header level, item level and schedule line level available in LO, you can choose at which level you want to extract your data and switch off others, which results in reduced data.

we do not have this flexibility with LIS structures

with Plug-In 2001.2 S2xx-Structures have been replaced by Logistics Extraction Cockpit. However, R/3 releases 4.x support S2xx-Structures and Logistics Extraction Cockpit in parallel.

With new LBWE extractors there are a lot of benefits:

- Detailed Extraction: extraction can be deactivated (e.g. Schedule Line Data) leads to leaner extractors with less volume.

Document Changes: only BW-relevant data changes will be updated (less upload volume).

- LIS-Tables are not updated reduced data volume due to avoided redundancy.

- Update with Batch-Process (V3) -> no load on daily business (but now there are available different delta methods as the direct delta...)

- No LIS-Know How necessary.

- Functional Enhancements easy to be done.

- Central, uniform maintenance tool for logistics applications (LBWE)

- No Delta-Tables (SnnnBIW1/-2) no double update, no double Data-Storage

- A lot of flows are covered: Purchasing,Inventory Controlling, Shop Floor Control, Quality Management, Shipment, Sales, Shipping, Billing, Plant Maintenance, Customer Service, Retailing....
