| Explain Selection field, Hide
field, Inversion and Field only Known
What is meant by Selection field, Hide field, Inversion and Field only Known exit? What is the Use of these? by: Anoo Selection When scheduling a data request in the BW Scheduler, you can enter the selection criteria for the data transfer. For example, you may want to determine that data requests are only to apply to data from the previous month. If you set the Selection indicator for a field within the extract structure, the data for this field is transferred in correspondence with the selection criteria in the scheduler. Hide field You should set this indicator to exclude an extract structure field from the data transfer. As a result of your action, the field is no longer made available in BW when setting the transfer rules and generating the transfer structure. If you don't want to see this this ..you set this field and you can't see in the BW which is available in extract structure. Inversion
If the option Field recognized only in Customer Exit is chosen for the field, this field is not inverted. You cannot activate or deactivate inversion if this option is set. Field only known:
For Example: You had posted one record in to the cube. All the key figures are updated (some are added and some are substracted). But you want to revert it back. So what you can do is if your data is present in the PSA. You can reverse post that request so that all the signs of the key figures are reversed( i.e addition becomes minus and minus key figures becomes additive) so that the net key figure change is nullufied. i.e., total change is Zero. In such cases, only those key figures which have "inversion" set will be reversed.
