Complex Formula

Question

I need to create a formula for this requirement:
Business Warehouse ABC Analysis report will be designed to rate and rank each material within the total inventory of one Plant with an ABC Indicator value. The process is as follows:
1. Materials are sorted highest to lowest based on number of material movements in the period.
2. The total value of the movements is calculated for each material by applying the standard cost to the quantity of movements = Cost of Goods Sold (COGS).
3. The cumulative percentage of Cost of Goods Sold (COGS) is calculated, moving from highest to lowest movements.
4. An ABC Indicator is assigned to each material based on its position in the cumulative COGS using the selected u201CAnalysis Strategyu201D. For example:
u2022 less than or equal to 70% = A
u2022 greater than 70% but less than or equal to 90% = B
u2022 greater than 90% up to 100% =C.
5. ABC Indicator u201CDu201D is assigned to materials with both no movements and zero COGS.
6. ABC Indicator u201CNu201D (new) is assigned only to u201CCu201D or u201CDu201D items for which material masters were created within a specified number of months prior to the date of the ABC Analysis.
Please advise

Answer 1

. Materials are sorted highest to lowest based on number of material movements in the period.
2. The total value of the movements is calculated for each material by applying the standard cost to the quantity of movements = Cost of Goods Sold (COGS).
3. The cumulative percentage of Cost of Goods Sold (COGS) is calculated, moving from highest to lowest movements.
4. An ABC Indicator is assigned to each material based on its position in the cumulative COGS using the selected u201CAnalysis Strategyu201D. For example:
u2022 less than or equal to 70% = A
u2022 greater than 70% but less than or equal to 90% = B
u2022 greater than 90% up to 100% =C.
5. ABC Indicator u201CDu201D is assigned to materials with both no movements and zero COGS.
6. ABC Indicator u201CNu201D (new) is assigned only to u201CCu201D or u201CDu201D items for which material masters were created within a specified number of months prior to the date of the ABC Analysis.
1. I'm guessing you can sort by Movement Amount (descending).
2. COGS * Movement Amount
3. RunningSum(Percentage([COGS * Movement Amount]))
4. Create an alerter based on 3. <=.7 = A, <=.9 = B else C
5. Create a variable to evaluate this condition and insert the variable or create an alerter based on it.
6. As above, using RelativeDate() as the basis for your formula.
I can't be any more exact but it should give you a good idea of how to tackle it.
