Good day!

I have a problem I can't solve in VBA. I have two tables, the first one with three columns: The name of players (distinct), date when they are available from and date when they are available to.

In the second table I have four columns. One date column, one column that contains slots that players need to be assigned to, thrid column stating if the slot is available on a given day and the forth column is the one that needs to be filled out.

The problem is that I need to fill out the slots each day with the players available, no player can be in two or more slots. So the VBA code should check which players are available based on given dates and fill out the slots available. In case there aren't enough slots available for all the players, I would need to know which players were left out. In the cases where the slots are more than the players, it should simply be empty, like in the file attached.

I hope this is clear. Please let me know if anything is unclear

Hi and welcome to MrExcel board!

Hi DanteAmor


I apologize for not using the XL2bb, this was my first post and from here on I promise to use it :D
And thank you kindly for such a quick and good response! It really helped a lot. I do wonder though if the code would need major adjustments if the available from and to dates would be transformed into a single column with available dates, since players might be available f.ex. 1.8.22, 15.8.22 and 31.8.22. Do you have an idea how the code would need to be adjusted for this? So if a player has been asigned a slot in the second table then he should not be assigned another one.
This time I'm attaching the Xl2bb table in the post! ;)

Best regards,
Sveppi

Hi again DanteAmor!

I'm wondering if I can bother you with a slight follow up question regarding the problem. Now the code takes the first slot in table b and finds if any players are available to assign to that slot, then the second slot in table b and etc.. Is it possible to change that into to assign the players into table b based on their order. The idea is to put a custom sort column in table a where a player has numerical values (1, 2, 3... etc.) and sort table a based on that column. In the attached table we can see that the most preferred date for John is 3.8.22, that slot is available in table b so John is assigned to that slot. Next up is Smith, his preferred date is 7.8.22, that slot is available in table b so he is assigned into that slot. Next up is Anna and she is assigned to slot on the date 6.8.22. Then it's Alan, his most preferred date is 5.8.22, but no slots are available then. Next up is Eric and he takes his most preferred slot on the date 2.8.22. Now Alan is still without a slot since there were no slots available on his preferred date. His next most preferred date is 1.8.22 (the next row where his name is in table a) and that slot is available in table b, so he is assigned to that slot.

Is it possible to change the code to take this into consideration, or is it perhaps a major adjustment that takes a lot of time?

And thank you for all the answers :)
