Hello Fernando,
Info-structures can be rebuilt. There is no permanent loss in these. Steps:
- Set up the statistics first for the Info-structure to a temporary version. Means building the statistics to a temporary version into the same info-structure table. The tcode varies according to the Info-structure. In your case the Tcode is OLI4 . Using this tcode you generate a temporary version &(0 of statistics. (Means you will give this value in the Save under versionfield). Give any name such as date etc in the Name of the run field. Hope I need not tell that you'll give S026 in the field Info structure to be set up. This operation usually takes long.
- Then use Tcode OLIX to copy this version to real version 000. How to do this is enter your infostructure (S026) in the initial screen > click on Copy + Delete push button, enter &(0 in the source version and execute. This operation does not take long. And all your lost data is restored.
Please have a trial in Dev servers to experience what is happening. As I said, there is nothing to fear while working on setting up of Info-structures as we can always rebuild when we know the steps.
My key area being Plant maintenance, I did not rebuild S026 ever (In my case the first tcode is OLPM and of-course the second one is OLIX for all.). I usually run this set up in the late in the evenings or on Off-days such as Sunday.
Good luck
