How do I fill the variables with data from 2 datasets more a list loop

[RobertHB]

Hello,

I'm new on SAS and I'd like to do this:

I have this three datasets:

Dataset01 (DS1):
Id  | Begin_date | End_date
d   |01jun2022   |10jun2022
b   |02jun2022   |06jun2022
c   |02jun2022   |07jun2022

Dataset02 (ds2):
Date       |
05/06/2021 |
06/06/2021 |

Dataset03 (ds3):
id |max_days |
a  |3        |
b  |3        |
c  |2        |
d  |2        |
e  |4        | 
f  |5        |
g  |2        |
h  |3        |
i  |4        |
j  |2        |
k  |4        |
l  |4        |
m  |3        |
n  |3        |
o  |5        |
p  |4        |
q  |3        |
r  |3        |

Output condition.a1: every day of the year is one row

Output condition.a2: each day must have 7 ids on the row

What i'd like to do is this:

a.Fill the variables with the ids from Dataset01, daily;

b.If the number of ids for one day is not enough, fill with ids from Dataset02

Condition.b1. can't repeat the same id on a day
Condition.b2. max number of times the id can fill the blanks before pass to next id: Dataset03.max_days
Condition.b3. days listed on Dataset02 do not count for the condition.b2 (above)

c.When the list of ids (Dataset03) is over, start again from the beggining.

Output wanted:

Date      |var_01  |var_02  |var_03  |var_04  |var_05  |var_06  |var_07  |
01jun2022 | d(DS1) | a(ds3) | b(ds3) | c(ds3) | e(ds3) | f(ds3) | g(ds3) |
02jun2022 | d(DS1) | b(DS1) | c(DS1) | a(ds3) | e(ds3) | f(ds3) | g(ds3) |
03jun2022 | d(DS1) | b(DS1) | c(DS1) | a(ds3) | e(ds3) | f(ds3) | h(ds3) |
04jun2022 | d(DS1) | b(DS1) | c(DS1) | e(ds3) | f(ds3) | h(ds3) | i(ds3) |
05jun2022 | d(DS1) | b(DS1) | c(DS1) |        |        |        |        |
06jun2022 | d(DS1) | b(DS1) | c(DS1) |        |        |        |        |
07jun2022 | d(DS1) | b(ds3) | c(DS1) | f(ds3) | h(ds3) | i(ds3) | j(ds3) |
08jun2022 | d(DS1) | b(ds3) | c(ds3) | i(ds3) | j(ds3) | k(ds3) | l(ds3) |
09jun2022 | d(DS1) | i(ds3) | k(ds3) | l(ds3) | m(ds3) | n(ds3) | o(ds3) |
10jun2022 | d(DS1) | k(ds3) | l(ds3) | m(ds3) | n(ds3) | o(ds3) | p(ds3) |

I don't understand what you are trying to do.  What is the actual business problem that it trying to be solved by this?

Why are there ID numbers in two different datasets?

What is the difference between the ID numbers in the first dataset (can you give this dataset more meaningful names? that might help explain what role they are serving) and the ID numbers in the third dataset.

What is the role of the dates?  Why are there DATE variables in two of the input datasets?  What is the relationship between the input dates and the output dates?

Hello, tks for ur reply.

The business problem is: out of office schedule. I cant't have more than 7 employees off frim the office in one day.

Ids=employee id

Dataset01 is a vacation dataset, with the employee id, beginning and end period.

Dataset02 is the holiday and weekend list.

Dataset03 is the list of all employees with the number of home-office days (according their work contract). It's a looping list.

Tks.

Maybe you should try a join then use Proc Transpose.
