The new linked table links to the original source table. For example, if you export a linked table named Employees1 in the Sales database that is linked to the Employees table in the Payroll database, the export operation creates a linked table in the destination database. The new linked table links directly to the Employees table in the Link Tables Using Pivot Tables in Excel. We will link tables using the pivot tables in this

Performance. The Start logic is not necessary for a SQL Server based system to get the best level of performance. Limited Report Writer features when using both SQL and C-ISAM data This section provides useful information that you should be aware of when defining and running reports that access data from both SQL Server tables and C-ISAM files in the same report. Limits The following table defines the limits for the Report Writer: Description Limit Maximum ISAM record length 4000 Maximum ISAM key length 200 Maximum alphanumeric field length 255 Maximum numeric field size 15.6- Maximum columns per table 200 Maximum column conditions per report 200 Maximum linked tables per report 12 Maximum 1-Many linked tables per report 2 Maximum columns per report 200 Maximum columns per heading section 100 Maximum columns per group heading section 100 Maximum columns per detail section 100 Maximum columns per sub-total section 100 Maximum columns per total section 100 Maximum number of user variables 100 Maximum number of unique strings per report 100 Maximum number of unique numeric constants per report 100 Maximum report conditions 30 Maximum level of brackets in conditions 10 Maximum columns per sequence 10 Maximum sequences per report 10 Maximum sub-total levels and groups 5 Maximum user variables conditions per variable 3 Maximum lines in the page heading 10 Maximum number of run-time prompts per report 10 Maximum fields per user variable 12 Limitations when using a mixture of ISAM and SQL tables in the same report If you intend to use a combination of ISAM and SQL tables in the same report, you must ensure that the primary table and any 1-Many linked tables are SQL Server-based. You can include 1-1 linked ISAM tables in the report. The Primary table cannot be an ISAM table if you are using mixed SQL and ISAM tables. Permissions (table and column) Each table and column can be assigned one of the following permissions: None - No Access Read Read/Write The default should normally be set to Read only. You use the Browse on Data Dictionary Tables Data Dictionary Tables program to define table access. You use the Browse on Data Dictionary Columns Data Dictionary Columns program to define table access. The lower access setting of the table and column permission is used to determine the actual access allowed. This is shown in the table below: Table Access Column Access Actual Column Access

Think that in order to fit what you are wanting to accomplish into Airtable (as opposed to in a spreadsheet), you need to be able to map it to a data model. I’m not an accountant, but I’m a fair hand at building data models. However, I’m struggling to wrap my head around what your data modeling needs are here.An example of what I mean by fitting this to a data model is like this - if I want to model a budgeting system in Airtable, I need, at minimum:the concept of an account - so I need a Table for Accounts, where each record represents an Account and can reflect that account’s balancethe concept of a transaction - so I need a Table for Transactions; I want a transaction to belong to an account, so I need there to be a linked record relationship between the Transactions Table and the Accounts Tablea transaction needs to be able to be of the type Debit or Credit - so I need some way to model that in the Transactions Table, maybe with a Single Select field that can toggle the value as being positive (a credit to the Account it’s linked to) or negative (a debit from the Account it’s linked to)the Accounts table can now roll up its balance by SUM’ing all its credit and debit transactions… and so on…Since the escrow accrual table is based on the closing/first payment date, I think there would only be 12 different table versions (closing date is January through December). The amounts will be different on each table though since the summer/winter/hoi will vary per record.Based on your example above, could we get by with a table that just has 12 different escrow accrual tables and then somehow plug the values into that (and read the results)? I’m not sure how this works in Airtable. If you have a basic structure suggestion, I will research and try and figure it out. I’m lost on how to start. Thank you again for your time.
