3.     DETAILED FUNCTIONAL REQUIREMENTS
3.1.     Functional Specification
Interdepartmental Contract Accounts are identified (Table: FKKVKP Field Name: KOFIZ_SD = “02”) and grouped together under a particular Group ID (FKKVKP-ZZ_REF_GRP_NUM). These accounts need to be reported on in a schedule for that particular department. The schedule will be executed using the Interdepartmental Group ID and the Billing Key Date on table ERDK.
The Billing Key Date (ERDK-BILLING_PERIOD) is used to better identify a document because an allocation to a certain date can be made. A billing document can, for example, be allocated to a certain month, although the billing period exceeds this month. If several billings are invoiced, they can be grouped together by billing key date. Each Invoice document has this field populated as each invoice will belong to a particular month.
Table ERDK is the invoicing table and has the contract account number (VKONT) linked to a specific invoice (Table field: OPBEL). This field can be used to link to table DFKKOP on field Reference (Table field: XBLNR) which is the table for all items contained in the invoice document. The service charges will be obtained by looking at specific divisions (DFKKOP-SPARTE).
Miscellaneous Charges (Sundries) linked to each respective service will be obtained by looking at line items per division (DFKKOP-SPARTE) posted between the last invoice and the current Invoice.
The Balance brought forward is the previous net invoice amount in table ERDK; this can be achieved by determining the billing key date less than the current billing key date. E.g if the current Billing key date is 2006/10, then balance brought forward will be 2006/09.
Payments are identified with ORIGIN = ’05’ and ‘06’ in table DFKKKO. Get the document number (DFKKKO. OPBEL) equal to the document number (DFKKOP.OPBEL) and get amount (DFKKOP.BETRW) if the document was posted between the last Invoice and the current Invoice. It is important to note that Payments can be posted on the same day as the invoice posting date. These payments will be considered for the next schedule run.
IMPORTANT NOTE: Items settled within the specified input period of the report must be displayed on the schedule. With this in mind, the item settled i.e. the original Debit must be included in the Balance Brought Forward and the Payment or Credit adjustment must be reflected on the schedule, this will then give a true reflection of the previous account balance and subsequent payments or credit adjustments made.
A grand total per Interdepartmental Account will be displayed for each of the line item amount fields.
It is also required that the contract account’s street address and stand number linked to the specific account be shown on the schedule, these are found in table EVBS and EHAUISU respectively.
The following rules will apply:
1.  The Township field is obtained from table EVBS field CITY1
2.  The Stand no field is obtained from structure EHAUD field STANDNO; used HAUS to search
3.  The house no. is obtained from table EVBS field HAUS_NUM2
4.  The street field is obtained from table EVBS field STREET and is concatenated with the house no above.
How to get address information:
-     Get all contracts linked to a contract account in table EVER
-     Link EVER and EEINV with the contract
-     Get the premise number from EEINV and link table EVBS.
-     Select the above (1-4) fields from table EVBS.

3.9.     Totalling
Balance B/F:
Previous net invoice amount in table ERDK, generally auto settlement and account maintenance would run to settle all debit amounts. 
Payments:
Payments are identified with ORIGIN = ’05’ and ‘06’ in table DFKKKO. Get the document number (DFKKKO. OPBEL) equal to the document number (DFKKOP.OPBEL) and get amount (DFKKOP.BETRW) for the same Posting Date (DFKKOP.BUDAT).
Service Charges per account on ERDK:
Get Contract Account (VKONT) from ERDK, link to contract account in DFKKOP, where ERDK.OPBEL = DFKKOP. XBLNR and Division(SPART) = ’01’  for Electricity, ‘03’ for Water, ‘04’ for Sewer, ‘05’ for Industrial Effluent, ‘06’ for Refuse and ‘09’ for Property Rates.
Total Due: Sum the Sub-Total and all service charges
Total: Sum of all the columns
Note: For field AUGOB in DFKKOP, if the field is populated with an ‘X’ it must be excluded from the calculation on the report. For field AUGRD in DFKKOP, if the field is populated with “05”, it must be excluded from the report, as it is a reversed item which the customer will be unaware of and subsequently must not be displayed on the report.
3.10.     Sorting
The report output will be sorted by Interdepartmental Group ID and Contract Account Number.
3.11.     Page Breaks
Page breaks will be used where necessary to prevent overflow of retrieved data. Each new page should have the headings printed at the top. Each Interdepartmental Group Account should start on a new page.

Answer 1

Verify your repository design and make sure that you have defined count aggregate on fact column. You would also need to define the content level of each dimension in fact table.
